Abstract: Systems and methods for determining whether a particular feature or change implemented in at least one test store causes a significant change as compared to one or more control stores are discussed. More particularly, techniques for using a time-series clustering algorithm to identify comparable sister stores to a store in which a feature change is being considered are described. Once the sister stores are identified a testing module can perform an A/B testing so as to validate whether a particular feature change being implemented in the test store causes a significant change as compared to the control stores.

Abstract: A computer implemented system and method for managing inventory includes determining a value for a parameter indicative of a response time associated with at least one transaction for an item of inventory. In conjunction with executing any particular transaction, an inventory update method is selected from a plurality of inventory update methods based at least in part on the determined value. A record indicative of an inventory level of the item is modified according to the selected inventory update method. A first inventory update method alters a locked inventory record and a second inventory update method alters a freely accessible proxy for the locked inventory record.
